I am contemplating taking my truck up to Silver Lake soon. The truck is a 2wd 4.3l 1500 Chevy. A couple of my buddies think it is going to do fine up there, as do I, but I have had a couple people tell me that I am not going to make it anywhere if I don't have 4wd. I have bfg all terrains on the truck which have plenty of tread on them. Do you think I will have a problem making it up any of the hills if I go up there?
